2)WATER CONNECTION
Install a 55°C water tap in a well accessible place, terminating in a 3/4"
fitting, which the pipe strainer and inlet hose shall be connected to.
Carefully comply with any national or regional regulations in force.
The operating pressure should be neither less than 2 bars or greater that 4
bars (200/400 kPa). If water pressure is inferior then 2 bar, a pressure
increase pump is necessary. If water pressure exceeds 4 bar, a pressure
reducer is necessary.
In order to obtain best results, it is suggested that the water supply have a
hardness not greater that 8 Clarke.
3)WATER DRAIN
Arrange a water drain towards the floor with siphon and connect the machine
with the flexible tube given with the machine, so that it leans towards the
drain. Moreover, make sure that the hose does not have constrictions.
Make sure that the building drain tubing withstands temperatures up to 70°C.
4)RINSE AID DOSAGE
Make sure that rinse aid suction hose is correctly installed in it’s proper
container. The dosage is automatic with the adjusting of the screw "I", which
after screwing to a full stop unscrew two turns. At this point the machine
automatically takes the necessary liquid for every rinse: during the washing
operations, check that the liquid of the container does not run short.
For filling the dosing tube, start the machine (Q1 in pos.RED) without
plugging the overflow in: at that point switch the machine on (pos.RED) and
off (pos.GREEN) . Repeat this operation several times at intervals of few
seconds, until the rinse aid reaches the injector. Wait until the machine
reaches the correct temperature (lamp "H2" on). Make some empty cycles,
then try to wash: if the objects washed show some drops, this means that the
rinse aid is insufficient. On the contrary, the presence of marks can mean that
there is too much rinse aid or the water is too hard. The regulation can
change according to the kind of rinse aid.
5)DETERGENT DOSAGE
With the screw on the side of the detergent pump, close completely the
product intake, then slowly open the screw until the desired intake quantity
has been reached. The correct quantity is indicated by the detergent supplier.
Check that the intake of the pipe during the rinse cycle is as preset. (1cm =
1g approximately). Maximum intake or delivery distance: 2 meters.
